I'm no mechanical engineer, but the two vehicles mentioned (and most cars
today) are unit body. There is no big heavy frame like you'd find on your

As for the bumper's crash bar, that thing is going to be attached to the
unit body, not a big heavy frame. Either through the trunk sheet metal or
through the bumper bar, you are relying on the hitch being bolted to
sheet metal.

I'd go with the canned solution. My reasoning is that, if an auto
manufacturer offers a hitch, it probably has some real-world testing
behind it (for liability and reputation reasons). The after market
solution probably copies what the auto manufacturer created. Hitches
are rated for towing specific weights. Pulling a freight train might
tear apart your sheet metal. But pulling a 600 boat, with 60 lbs on
the tongue, shouldn't stress even a Class I hitch.

That's my 2 cents.
